Answer: He can load at most 20 boxes.

Step-by-step explanation:

Let x = Number of boxes.

Then, Weight of 75 boxes = 75x

Also, Weight of worker = 200 pounds

So total weight in elevator =  Weight of 75 boxes + Weight of worker

=  75x  +200

A warehouse elevator can hold 1750 pounds.

∴ 75x  +200 ≤ 1750

⇒ 75x ≤ 1750 -200

⇒ 75x ≤ 1550

⇒ x ≤ 20.67   [Divide both sides by 75]

It implies the maximum number of boxes it can hold = 20

Hence, the true statement is

He can load at most 20 boxes.
